The outside of 61, and by sealing ring 80 press seal in pushing block groove 61.This utility model is by pushing block
Sealing ring 80 in groove 61, and make the bolt head of bolt 70 be crimped on the outside of pushing block groove 61,
And by sealing ring 80 press seal in pushing block groove 61, owing to bolt head is direct and piston thrust block 60
The outside cooperation of pushing block groove 61, namely directly piston thrust block 60 is fixed on escapement 50, phase
Fixing side than the cylindrical protrusions 31 on the diaphragm 30 of bolt head extruding turnover in prior art
Formula, it is to avoid pullling between piston thrust block 60 and diaphragm 30, thus prevent because pullling deformation
The gap caused increases, it is to avoid infiltration, improves reliability.
In this utility model, bolt 70 is unlike rounding in prior art, and this practicality is new
The bolt head of the bolt 70 of type is vertical with screw rod to be connected, and at the root formation right angle connecting portion of screw rod,
Namely bolt head root right angle (as shown in label B in Fig. 6,8 and 10), it is thus possible to be conducive to pressure
Closely seal 80 and piston thrust block 60.Specifically, this practicality is illustrated in conjunction with Fig. 6 to 11 new
The embodiment of type.
In first embodiment as shown in Figure 6 and Figure 7, diaphragm 30 is made up of elastic plastic material,
For triangle with rounded corners, it is divided into upper and lower surface, upper surface to be uniformly distributed three piston thrust blocks 60
Installing zone, each piston thrust block 60 installing zone has a cylindrical protrusions 31, cylindrical protrusions 31
On there is bolt hole 32, accordingly, piston thrust block 60 is provided with assembling through hole 62, assembling
Through hole 62 coordinates with the outer peripheral face of cylindrical protrusions 31,
It addition, be provided with circumferential positioning structure between diaphragm 30 and piston thrust block 60, it is preferable that
Circumferential positioning structure includes the multiple positioning convex being arranged on cylindrical protrusions 31 root, piston thrust block
On 60, corresponding multiple positioning convex are provided with multiple detent.Further, positioning convex is for arranging
At four trapezoidal locating pieces 33 of the root of cylindrical protrusions 31, detent is for being correspondingly arranged at work
Four trapezoidal locating slots 63 on plug pushing block 60, trapezoidal locating piece 33 is with trapezoidal locating slot 63 one by one
Corresponding matching, plays circumferentially positioned effect.
On equally distributed three piston thrust block 60 installing zones of diaphragm 30 upper surface, piston thrust block is set
Coordinate three compression chambers constituting booster pump, compression chamber with three chambers of piston valve cover 20 after 60
Interior piston thrust block 60 drives diaphragm 30 to do reciprocating motion repeatedly under the drive of escapement 50,
Water is sucked from low pressure chamber pressure, and compressed chamber presses to altitude chamber, it is achieved function of increasing pressure.
Specifically, as it is shown in fig. 7, in the first embodiment, after assembling, cylindrical protrusions 31
Top is concordant with the top of pushing block groove 61, namely cylindrical protrusions 31 is equal to assembling through hole 62
Height and the height sum of pushing block groove 61, assembling through hole 62 and the cylinder of diaphragm 30 upper surface
The external diameter of shape projection 31 is equal, both through hole alignment, then by bolt 70 and following escapement 50
Fixing.
More specifically, in the first embodiment, the screw root of bolt 70 is right angle, bolt head
Diameter is more than pushing block groove 61 diameter, is provided with sealing ring 80, it is preferable that close in pushing block groove 61
Seal 80 uses O-ring seals, and the diameter of the cross section of O-ring seals is more than pushing block groove 61
Height.When bolt 70 is urgent, the O shape that bolt head section is pressed down against in pushing block groove 61 is close
Seal so that it is compressive deformation, forms end face seal, prevents the water penetration of compression chamber from damaging to power-section
Motor 1.The outer of bolt head is directly squeezed in the piston thrust block 60 part beyond pushing block groove 61
On so that piston thrust block 60 is directly connected by bolt 70 with escapement 50, it is to avoid pull diaphragm
30 and cylindrical protrusions thereon 31, improve reliability.
As shown in Figure 8 and Figure 9, in the second embodiment of the present utility model, with first embodiment not
With, in a second embodiment, the top of cylindrical protrusions 31 is flat with the bottom of pushing block groove 61
Together, namely assembling through hole 62 height equal with the height of cylindrical protrusions 31, on 70 dozens, bolt
Time tight, bolt head root section is pressed down against the O-ring seals in pushing block groove 61 so that it is pressurized
Deformation, forms end face seal, prevents the water penetration of compression chamber from damaging motor 1 to power-section.
In a second embodiment, owing to reducing cylindrical protrusions 31 height, so that crimp
O-ring seals can directly contact the edge of sealing bolt 70, compare first embodiment, it is possible to
Improve sealing effectiveness further, prevent from running seeps water.
As shown in FIG. 10 and 11, in the 3rd embodiment of the present utility model, in first embodiment or
On the basis of person's the second embodiment, increasing and be provided with pad 90, pad 90 external diameter is more than pushing block groove
The diameter of 61, when bolt 70 is urgent, bolt head root section is pressed down against gasket seal 90, and then
O-ring seals in extruding pushing block groove 61 so that it is compressive deformation, forms end face seal, prevents
The water penetration of compression chamber damages motor 1 to power-section.By arranging pad 90, improve reliability, can
So that the diameter of bolt head is less than the diameter of pushing block groove 61.
This utility model additionally provides a kind of water purifier, uses aforesaid membrane pump, is prevented effectively from compression
Chamber is to the water leakage problems of power-section, it is achieved that compression chamber and the intact sealing of power-section, improve every
The reliability of membrane pump longtime running.
As can be seen from the above description, this utility model the above embodiments achieve following skill
Art effect:
According to membrane pump of the present utility model and water purifier, by the sealing ring in pushing block groove 61
80, and make the bolt head of bolt 70 be crimped on the outside of pushing block groove 61, and sealing ring 80 is pressed
It is enclosed in pushing block groove 61, owing to bolt head is directly and outside the pushing block groove 61 of piston thrust block 60
Portion coordinates, namely is directly fixed on escapement 50 by piston thrust block 60, compared to existing technology middle bolt
The fixed form of cylindrical protrusions 31 on the diaphragm 30 of head extruding turnover, it is to avoid piston thrust block
Pullling between 60 and diaphragm 30, thus prevent the gap caused because pullling deformation from increasing, keep away
Exempt from infiltration, improve reliability.
The foregoing is only preferred embodiment of the present utility model, be not limited to this practicality new
Type, for a person skilled in the art, this utility model can have various modifications and variations.All
Within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made,
